미 연안경비연구개발센터(USCG RDC)와 미 해양거버넌스(MARAD)는 선박평형수 확인을 위한 준수 도구로서 다양한 형광 기반 기구의 효율성에 대한 타당성 연구를 공동 지원했다. 현장과 실험실 샘플의 블라인드 테스트는 미국 내 세 곳의 다른 장소에서 오는 9월 시행될 예정이다.

The United States Coast Guard Research Development Center (USCG RDC) and United States Maritime Administration (MARAD) have co-sponsored a validation study of the effectiveness of variable fluorescence-based instruments as compliance tools for ballast water checks. The study began on Monday, June 1, in Key West, Fla.

 

Blind testing of field and lab samples will be conducted through September, 2015, at three different sites in the United States. Pam Mayerfeld, Turner Designs vice president of Marketing and Sales, provided initial training on the company's Ballast-Check-2 Handheld PAM Fluorometer and then stepped back to observe as the scientists proceeded to do the testing.

 

"I am very impressed with their detailed preparation for the study," said Mayerfield. "They fully defined all sampling protocols and cell-counting methods. They're looking at several different natural waters as well as algal monocultures with known interferences. They have an array of forms in place so data will be collected consistently across the three sites. We are very excited to be part of this validation and anxious to see the results."

 

The Turner Designs Ballast-Check-2 is one of three fluorometers included in the validation study and is a small, lightweight, highly durable, battery-operated PAM fluorometer. It is ideal for quick indicative compliance checks of the ballast water regulation for living algal organisms in the 10-50μm size class. Factory set, the Ballast-Check-2 is ready for use right out of the box, no calibration is necessary, though a calibration check standard is included for confirmation.

 

Accordingly, simple one-button measurements display estimates of both algal abundance and algal activity, providing a quick indication of risk for gross exceedance of the regulation. Results are displayed in less than one minute and are logged internally for future downloading.
